# Fetch Vectors

> Fetches the vectors with the provided ids.

You can fetch vector values or metadata of one or more by providing
their vector ids or id prefix.

<Tip>
  Vectors will be fetched from the default namespace by default.
  You can use a different namespace by specifying it in the request path.
</Tip>

## Request

<ParamField body="ids" type="string[]">
  Array of vector ids to fetch.
</ParamField>

<ParamField body="prefix" type="string">
  Prefix of vector ids to fetch.

  <Info>When you fetch vectors with an id prefix, at most `1000` vectors will be returned.
  If there are more vectors, please use the [range](./range) API with an id prefix.</Info>
</ParamField>

<ParamField body="includeMetadata" type="boolean" default="false">
  Whether to include the metadata of the vectors in the response, if any.
  It is recommended to set this to `true` to easily identify vectors.
</ParamField>
<ParamField body="includeVectors" type="boolean" default="false">
  Whether to include the vector values in the response.
  It is recommended to set this to `false` as the vector values can be
  quite big, and not needed most of the time.
</ParamField>
<ParamField body="includeData" type="boolean" default="false">
  Whether to include the data of the vectors in the response, if any.
</ParamField>

## Path

<ParamField path="namespace" type="string" default="">
  The namespace to use.
  When no namespace is specified, the default namespace will be used.
</ParamField>

## Response

<ResponseField name="Vectors" type="Object[]">
  Array of vectors in the same order they provided in the ids array.
  Array elements can be `null` if no such vector exists with the provided id.
  <Expandable defaultOpen="true">
    <ResponseField name="id" type="string" required>
      The id of the vector.
    </ResponseField>
    <ResponseField name="vector" type="number[]">
      The dense vector value for dense and hybrid indexes.
    </ResponseField>
    <ResponseField name="sparseVector" type="Object[]">
      The sparse vector value for sparse and hybrid indexes.
      <Expandable defaultOpen="true">
        <ResponseField name="indices" type="number[]">
          Indices of the non-zero valued dimensions.
        </ResponseField>
        <ResponseField name="values" type="number[]">
          Values of the non-zero valued dimensions.
        </ResponseField>
      </Expandable>
    </ResponseField>
    <ResponseField name="metadata" type="Object">
      The metadata of the vector, if any.
    </ResponseField>
    <ResponseField name="data" type="string">
      The unstructured data of the vector, if any.
    </ResponseField>
  </Expandable>
